I'm aware that there are a whole slew of products that serve to transmit the audio from an attached microphone (like a lavalier) wirelessly to a receiver unit.

I'm in search of just the opposite: a hip-mounted (or otherwise worn on one's person) device for receiving audio from a wireless transmitter source and sending into some regular attached headphones.

Bluetooth headphones don't cut it because of the latency and compression, and although there are lots of options for non-bluetooth wireless headphones, I'm looking for a device that lets ME choose the headphones and just does the wireless part.
